Log di atas adalah hasil catatan yang kita lihat di Open5GS. Cerita yang dapat kita sari-kan dari log di atas, kira-kira sebagai berikut,'

Dalam experimen eNB-S1 berupa srsRAN yang dijalankan pada Ettus B200 dengan IP address 192.168.100.238.
Pada jam 04:14:24.076 terlihat eNB-S1 yang berupa sebuah BTS (RAN) berhasil connect ke Open5GS. Hal ini terlihat dengan kata-kata "Number of eNB-UEs is now 1"
Pada jam 04:14:25.924 setelah eNB berhasil tersambung maka akan dibuka sesi di MME Open5GS. Hal ini terlihat dengan kata-kata "Number of MME-Sessions is now 1"
Setelah eNB connect dan sesi MME berhasil di tambahkan di Open5GS, selanjutnya eNB terbuka untuk menerima sambungan dari smartphone / HP.
Pada jam 04:14:25.924 terlihat ada request dari IMSI 510330000012344
Pada jam 04:14:26.224 terlihat dengan jelas bahwa handphone dengan IMSI 510330000012344 berhasil tersambung dengan baik.

Sebetulnya sebelum eNB-S1 berhasil connect, eNB-S1 gagal tersambung ke Open5GS. Hal ini terlihat pada jam 04:13:52.288 dan 04:13:52.289 dengan kayanya [Removed] "Number of MME-Sessions is now 0" dan "Number of eNB-UEs is now 0".
